Australian Cattle Dogs, widely called Blue Heelers or Queensland Heelers, were developed in nineteenth-century Australia to move cattle over long distances in heat and dust. They're compact and muscular, usually 35 to 50 pounds, with a short, weatherproof double coat in blue or red speckle. The coat is easy to keep up, though it sheds more heavily once or twice a year.
Heelers tend to be loyal, clever and watchful, often attaching to one person and staying reserved with strangers. Herding instincts can show up as nipping at heels or chasing bikes and joggers, which matters on busy Honolulu sidewalks and beach paths. Dogs vary, but most do best with daily training, a real outlet for their stamina, and a home where someone is around.
